Atmega 328 development board

Arduino UNO clone. The scematics were designed based on ATMega 328p datasheet to make it possible to use the product as a development board. The layout was then designed to fit in a two layered 53mm x 50mm circuit board. The board is compatible with official Arduino shields. After the layout was designed, the photo-masks were printed for PCB manufacturing and the PCB was etched. Then all the vias were drilled and soldered along all the other components.
The complete development board was then flashed and programmed using ISP-programming interface.
